NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-coco_debug-devel package and not the kernel-coco_debug-devel package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

net: ethernet: mtk_wed: fix use-after-free panic in mtk_wed_setup_tc_block_cb()

When there are multiple ap interfaces on one band and with WED on, turning the interface down will cause a kernel panic on MT798X.

Previously, cb_priv was freed in mtk_wed_setup_tc_block() without marking NULL,and mtk_wed_setup_tc_block_cb() didn't check the value, too.

Assign NULL after free cb_priv in mtk_wed_setup_tc_block() and check NULL in mtk_wed_setup_tc_block_cb().
